KDE Security Advisory: Kate backup file permission leak
Original Release Date: 2005-07-18
URL: http://www.kde.org/info/security/advisory-20050718-1.txt
0. References
CVE CAN-2005-1920
https://bugs.kde.org/show_bug.cgi?id=103331
1. Systems affected:
All maintained versions of Kate and Kwrite as shipped with
KDE 3.2.x up to including 3.4.0. KDE 3.1.x and older and
KDE 3.4.1 and newer are not affected.
2. Overview:
Kate / Kwrite create a file backup before saving a modified
file. These backup files are created with default permissions,
even if the original file had more strict permissions set.
3. Impact:
Depending on the system security settings, backup files
might be readable by other users. Kate / Kwrite are
network transparent applications and therefore this
vulnerability might not be restricted to local users.
4. Solution:
Source code patches have been made available which fix these
vulnerabilities. Contact your OS vendor / binary package provider
for information about how to obtain updated binary packages.
